People who have long been engaged in printing and packaging industry are very clear about the importance of printing rubber rollers. Because it has a direct relationship with the edition and is inextricably linked to product quality, whether you use offset printing, letterpress printing, gravure printing presses, or flexo printing presses are faced with how to select and debug printing rollers, how Master its technical standards and technical parameters and performance and debugging skills. If it cannot reasonably use and follow its operating rules, it will not only fail to produce ideal and excellent products, but will also damage the rubber rollers to prematurely “retir†and shorten the service life of the printing plates. It is difficult to adjust the printing roller to the optimal level and ideal point, and it is not possible to grasp it overnight. Because it does not have a fixed and a program, all the leaders will sum up, model, excavate, innovate and sort out a set of effective printing skills in the production practice of long-term production, which will produce for the enterprise of “high quality, high output, and low consumptionâ€. The main theme service. Therefore, it is very important for the tax to debug the printing roller.
The following is a comprehensive discussion and analysis of the selection, use, commissioning and maintenance of the printing roller, so as to better serve the production and play its due role.
The selection of printing rollers With the rapid development of the market economy, new equipment, new processes, new materials, especially new printing equipment are also produced. The replacement is also timely, which has played a positive role in promoting the rapid development of the packaging and printing industry. The printing equipment in China has become more technologically advanced, durable, and advanced. From the point of view of the international printing industry, there are data showing that some developed countries in Europe and America cannot but say that they are still ahead of us in terms of printing equipment. We are eager to catch up to shorten the distance between us. Although the domestic packaging and printing industry entered the printing machinery and printing equipment of many developed countries in the 1990s, when the printing rollers were used for a certain number of years and needed to be replaced, the domestic printing rubber rollers were far less than those of the original equipment.
In the past, printing companies were all equipped with "plastic rooms," which were specialized in the production of printing rollers and were heavily polluted. With the development of the printing industry and the replacement of equipment, traditional old-fashioned printing rollers have gradually been eliminated due to their inability to adapt to the needs of high-speed printing machines. Its disadvantage is that it can not adapt to the high temperature and high humidity environment, it becomes soft at high temperature, it becomes hard at low temperature, and it is even more unsuitable for printing gold and printed textured versions, which hinders the improvement of printing quality.
Into the 80's printing roller only to have a major revolution, the new roller from the weather conditions and strong, good corrosion resistance, but the high cost, so that small and medium enterprises are discouraged. With the rapid economic development, it is still well received by the majority of users. At present, the latest generation of printing rubber rollers produced in China is a bold innovation in the experience of absorbing similar foreign products, and the market is not small.
Debugging and Correct Use of Printing Cots Regardless of any type of printer or model, after the new equipment is in place, the technical staff of the power unit of the equipment must first install the printing rollers. The installation level of the rubber roller must be properly adjusted. It must be in close contact with the ink roller and the printing plate. Both are indispensable. Printing and packaging practitioners know that the height of the letterpress is 3.14mm, which is the same as the lead height. The PS version is relatively low at 1.2mm, so be sure to have a good idea when installing and debugging the rubber roller. If it is a printed product with a background color, the rubber roller can be adjusted to a lower value with an error of ±0.5 mm. This results in the same effect when the ink roller is transferred to the printing roller and reflected on the printing plate. If you don’t like this, there will be phenomena such as ink bars and ink channels.
When printing text, the height of the rubber roller is basically the same as the text version or slightly lower. This allows the printing roller to gently rub the plate so that the text is printed clearly and neatly. The small wear surface of the rubber roller is not easy to damage and can extend the service life of the printing plate. If each of our leaders can concentrate on research, we can save the purchase cost of rubber rollers and improve the quality of printing. So how can we master the correct use of rubber roller? The collar and the assistant must learn to use the glue stick. Before use, take the printing plate out and let the mixing stick extend horizontally and pull it out several times. The size of the ink dot on the glue stick will be displayed immediately, and the operator can print according to the different printing. Demand to determine the level of the printing roller, and then pin the top pin. In this way, the height of the rubber roller does not change during high-speed printing. If we are impatient with the use of rubber rollers and we are eager to make plans and save time, we will have the following conditions:
(A) The surface of the rubber roller has been damaged and the dregs have been dropped off, which has caused the characters to be printed and printed.
(B) The text is inconsistent, and even the appearance of the printed product is only printed but it is not ink.
(C) If the rubber roller is too tightly adjusted to the ink-transmitting rubber roller, the printing roller will be damaged to cause economic loss and equipment accidents.
The maintenance of the printing roller The high quality printing roller is the primary condition for the production of high-quality printed matter. The key to the offset printing technology is the control of the balance between the waterway and the ink path, while the balance of the ink and ink is the rubber roller and the ink roller. The key components, their quality can directly affect the product quality. This is especially true for gravure, emboss, and flexo. It is so important to maintain the printing roller. General printing companies maintain the equipment once a week, including the maintenance of the printing roller. The following methods are available for maintenance:
1. After the production operation is completed, clean the rubber roller and wash it twice;
2. Cleaning the printing roller must use the specified chemical agents such as industrial alcohol, etc. must not use corrosive solvents;
3. Take off the rubber roller as much as possible during the holiday break to prevent deformation under pressure;
4. The protection of the surface of the printing roller should be wrapped in newsprint and placed in a dark place.
The above is the use and maintenance of the printing roller, as long as we carefully study it will have a small interest. (Ji Ronghai) ("China Packaging News")
